Scope
|
Develop techniques and methodologies to determine or estimate TRP (with equivalent measurement metrics) by field measurements for both in-band and unwanted emissions (out of band domain and spurious domain) of 5G AAS. In order to facilitate checking compliance with national regulations and performing interference investigations.

Develop techniques and methodologies for measurement of 5G AAS in the field for the following:
1) In band signal evaluation (power limits, BEM)
2) Evaluation of unwanted emissions in the Out of band domain
3) Evaluation of unwanted emissions in the spurious domain
To determine TRP or find a method to estimate TRP with other measurement metrics.
The determination of the TRP should also be used to evaluate the compliance with existing regulations (e.g. ERC REC. 74-01).
Laboratory measurements of 5G AAS as discussed in other groups (such as ECC PT1 or ITU-R WP5D) could be used for comparison / verification of the proposed methods of 5G AAS measurements in the field. It is noted that the expertise on 5G AAS modelling in within ECC PT1. It is recognized that additional a priori information on 5G AAS e.g. details of the antenna (e.g patterns) are needed to develop or apply specific types of methodologies for field measurements.
The TRP measurement techniques / methodologies may be evaluated compared with existing 5G AAS information and models.
WI to be done in cooperation with ECC PT1 and ECC FM22. There may also be relevant work in ITU-R WP 5F and ITU-R WP 1C. It is noted that the deliverables for in-band and unwanted would be split into two.
ECC Report 345, “In-band measurement methodologies for 5G AAS base stations in the field” was published 7 October 2022 and fulfils objective 1 (In band signal evaluation).
